I have a 91 s5.It has a bnr stage 3 upgrade turbo and a rx7trix street ported motor.I have a full 3in exhaust,Fd fuel pump,greddy profecb,720 cc secondaries,Greddy 2 row Fmic with greddy BOV.Hks intake, FCD and thats it for now..
Now i was looking to go either stand alone or use a super afc.Obviously the standalone is expensive.But i was wondering which unit do u guys prefer and what part do i need and is most of the standalones for a 2nd gen plug and play or do u have to get all different kinds of maps..
Sorry for all the questions..I just sold the 3rd gen and i picked this up...i seen alot of people hit twelves without a stand alone and i was curious..

Thanks
Kevin

 

You have a 91, which means if you want to spend big money you can buy a Power FC from Japan and it'll plug right in.

Other alternatives are Haltech E6X/E11 and the Microtech units.

I have an E6K. Some are partial to Haltech, others to Microtech. The best answer is to go with whatever your tuner knows best.

FYI your fuel pump and injectors may hold you back in terms of attainable power.

 

interesting!!! How is installing the e6k in your car?Is it a plug and play or u need a good tuner to do it.?...Also what do u recommend for injectors then..

Thanks

 

Well, it's certainly not plug and play. Mine came with an unterminated wiring harness, so I had to wire all the sensors, the fuel pump, etc. Nothing involving the installation has seemed very hard, though. Somewhat tedious but not terribly difficult.

Of course, if you've got the cash then it's just as easy to have somebody else do it for you

As for fuel, I would upgrade to a Walbro or a Supra fuel pump and get either another pair of 720cc injectors for your primaries, or some larger injectors (1000cc, 1200cc, 1600cc are common sizes) for your secondaries and put the 720s in your primaries.

 

What about the LT-8 and LTX-8 systems that atkins rotary sells, are they decent managment systems?

 

Since you are just starting I HIGHLY recommend finding a local tuner, and talking to them. If you are comfortable with them; install the system they are most familiar with. A stand-alone is a wonderful tool: IF YOU KNOW HOW TO USE AND TUNE IT!

 

I am very biased towards Microtech LT-8 and LTX-8 systems. I currently have an LT-8 Installed in my personal vehicle. I have had some experience with Haltech and even megasquirt engine management systems, but for me the LT-8 is easiest to use and my tuner is local (he's my boss!) There are pages upon pages of debate regarding which management system is "better" pages upon pages about fundimental differences and such.

Check out the Engine management forum/section of rx7club and you'll find all the info your looking for.

Yeah i come from a 3rd gen so the easiest management was the Apexi power fc which was plug and play..It took no longer than 20 minutes to use and most tuners was use to it..So i was just curious what stand alone for a 2nd gen is like that..


thanx again

Just out of curiosity what kind of number do u think my car should produce?1/4 mile times..

 

My best guess? 13.0 or somewhere in that range.

Never can really tell unless we all know how well the engine/system is tuned.

Autronic... Zkeller may be the first in the US to put one in a third gen.. DAMN.. he has a ported motor and a turbo about the size of bass drum on that thing...

he had all sorts of problems trying to run 4 1600 injectors, the aussies said "yer squirters are too big", he put 4 Marren 950's in it and.... holy shiete... it idles perferctly... no misses, no blurpes, rock solid, I've never heard ANY 7 idle that good. And Smooth... there is no hitch whatsoever when the secondaries come in.

its got an Autotune feature where you hook up the wideband to it, tell the ECU what A/F you want to run at what boost level and give it a few runs and it sets itself...... DAMN......!!

Its freaking expensive, but if i didn't already have the Haltech, i'd be ponying up for it.

 

stay away from SDS. since you have to ask this question then my answer is obvious. GO with what your tuner knows.

 

Hey. The Power FC is available for series 5 cars, like I said earlier. You have to import it from Japan, though. Maybe Jason from RX7store could help you out, if you chose that option?

 

Thx for the info on the Microtech systems, Ive looked into them some more and they seem pretty good. And the ease of tuning will be helpfull since there are no professional tuners in my area, so I will be doing that all my self.

 

i had no idea you could hook up a power FC into a FC i have a 91 TII too, would you have to run premix with it or can it operate the meatering pump?

 

I'm considering ditching the haltech just to switch. Soooo bad *** but it is $$$

LIke others have said though; Generally, the best system is the one that your tunner knows how to use, or the one that you can get the best support in your area. I chose Haltech for those reasons.

The thing is, if I factored in the cost of my haltech, and then my cost to get it tunned, I'm creeping up on the autronic.

 

i think i am gonna go with a microtek unit..But what do i need?do i need any other necessities that are optional.I am gonna purchase the one that is around 800 or so the lt-8..

 

I'd recomend calling dave at fc3s.org. Great guy, very knowledgable and an authorized microtech dealer. He'll get you set up wiht anything you need.

how about a power FC in a FC

 

Get a Wolf EMS V 4.0... by far the best stand alone for the money... and no there not piggy backs.. I've had great luck with mine

My car ran a low 12 without stand alone (should've broke 11's only had a few runs, had 372 rwhp on 91 octane), just my extra injector set up (which I'm selling, PM for the specifics).

I believe that you shouldn't buy the stand alone that you think is the best, instead which one is used by the best local tuner. Often newer versions or better stand alone's add uneccesary features (such as throttle control). My advice is find the best local tuner and use the stand alone that they're most familiar with.
